Beschard · Bechaud
In the De Secretis manuscripts (Clavicula Salomonis de secretis, 17th c. — Dresden N.91, Rps 3352 II, Venice b.93) as «Beschard», with its power and its drawn character. This is the stratum preceding the printed Verum.
«Beschard In ventos, Tempestates, pruinas, hyemes, fulmina, nives, grandines, pluvias omnismodi, sive cum bufonibus, sive cum Sanguine, sive cum Lapidibus ciendas, vel compescendas Imperium habet.»
De Secretis · SLUB Dresden, Mscr.Dresd.N.91 · p.20-21 (ms.12-13)

This same character is also drawn (in red and green ink) in L'Art Magique (Wellcome MS.983, ~1709), the French witness closest to the printed Verum — public domain.

To make it rain: wash with seawater a circle traced on the ground; in the center, a heliotrope stone; on the right, engrave the character of Bescard, on the left, that of Elelogaphael; over the staff pronounce 'Heleluga phatel' and the sky will fill with clouds until they resolve into water.
